More than half of ESPN’s top 100 NFL free agents for 2019 are either signed or committed to a team as the first week of the new league year closes. Now is the time when smart and/or patient teams dig in and start searching for bargains that can help them in defined roles.

Who could those bargains be? Here are 15 of the top remaining players on the open market.

Note: Baked into this list are a number of long-standing market variables. Age is a major factor (the sweet spot is 26). Quarterbacks are overvalued for obvious reasons. Teams are more desperate for pass-rushers and outside receivers than they are for safeties or veteran running backs.

Age and a long injury history will limit his value. Most recently, two shoulder injuries cost him nine games in 2018. But he had 48 sacks in six seasons with the Lions, and a team with a plan to use him situationally could receive big dividends.
